The respect of the principle of equality before the law (a.k.a. universalizability) is not only a necessary but also a sufficient 
condition to logically demonstrate that the non-aggression principle (NAP) is the only possible non-arbitrary coercive rule.

This means that it is not logically possible to believe in the principle of equality before the law and not be a libertarian (e.g. be in favour of any form of state). Those who are, are objectively mistaken. Either they are fooled by the propaganda or they are part of it.
